Wireless communication system and time synchronization method thereof

摘要

A method for acquiring and maintaining Global Positioning System (GPS) synchronization is provided for use in the wireless communication system. The method includes receiving, by at least one Global Positioning System (GPS) receiver, GPS absolute time information and GPS information from at least one GPS satellite; transmitting, from the at least one GPS receiver, to a base station, reference time information generated based on the GPS absolute time information; and generating, by the base station, base station absolute time information based on the reference time information.
